SECTION 1
DESCRIPTION OF THE UNIT
The FB250 Air Filtration Box can treat 250m³/h and may be utilized in a
variety of applications where fume extraction and filtration is required. The
system is totally self contained and requires no connection to external
ventilation. Air is drawn into the unit via the duct inlet spigot/s or via an
optional articulated arm the contaminated air is passed through an
electrostaticaly charged pre-filter to remove particulate and then through an
Activated Carbon main filter to remove chemical fumes it then passes through
an optional HEPA filter before exhausting the air back to the laboratory. The
airflow is continuously monitored and will provide an audible and visual alarm
if the airflow drops below a safe level. The exhaust air is also monitored by a
hydrocarbon sensor to provide an indication of carbon filter condition.
